A simple dI/dt confusion, Anyone like to try & solve it ?

[Sanjay kumar]

According to calculation : -
1uH coil is giving me 50A/uS for 100uS,
If I use 4uH coil, it will give me 12.5A/uS for 400uS

What I am trying to ask specifically is : -
Will total time get increased by 4x ?
Or It will only take extra 4uS for current to reach 50A, then for the rest of the time - 100uS, It will continue at 50A ????

"It will continue at 50A"
By this I meant, 50A constant current flow for the rest 100uS.
Not rising 50A/uS.

I should have said "R that is 0.05 * 10 * (peak V) / (peak I)"
You could use small ohm resistors between each cap and the bar (probably of the order of 0.1 to 0.5 ohms each) but they have to be very high surge capable types.

Which kind resistor I can use ?? Like high wattage rating
Which won't blow up !

Out of interest, could you post up your schematic so far.

Ah, is that the exact circuit you are using? Ok, thanks.
